Fluorescein Isothiocyanate Isomer I (FITC), commonly referred to by its CAS number 3326-32-7, is a vital fluorescent labeling reagent, widely adopted in the scientific community for its robust performance in various biotechnological and biochemical applications. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize its significance and are dedicated to supplying high-quality FITC to researchers worldwide. Understanding the properties and applications of this compound is key for any laboratory aiming for precise and reliable results.

The core utility of FITC Isomer I lies in its ability to covalently attach to biomolecules, particularly proteins, through its reactive isothiocyanate group. This functional group readily reacts with amine functionalities (such as lysine side chains and N-terminal amines) on proteins, forming a stable thiourea bond. This linkage ensures that the fluorescent dye remains securely attached, allowing for consistent visualization and quantification in techniques like immunofluorescence, flow cytometry, and various immunoassays. For researchers looking to buy FITC protein labeling agents, the stability and high fluorescence quantum yield of this isomer are paramount considerations.

The bright green fluorescence emitted by FITC, with excitation and emission maxima typically around 492 nm and 518 nm respectively, makes it a versatile tool. It is compatible with the widely available 488 nm laser used in flow cytometers and many fluorescence microscopes. This broad applicability has cemented its status as a go-to fluorescent label in studies involving cellular imaging, protein localization, and diagnostics. Its use in medicine, agriculture, and animal husbandry for disease diagnosis further highlights its broad scientific impact.
